COTTON-GINNING- MACHINERY.

To all whom it may concern:

Be it known that I, RALPH E. Wilson, a citizen of the United States,residing at Dallas, county of Dallas, and State of Texas, have inventedcertain new and useful Improvements in Cotton-Ginning Machinery; and Ido hereby declare the following to be a full, clear, and exactdescription of the same.

The present invention relates to machinery for ginning cotton and is ofsuch character that it may be embodied in ginning machines beingmanufactured or, in many types of ginning machines now in use, it may becombined therewith or embodied therein without changing the presentrelation of the working parts or altering the form and construction ofthe gin framing or casing.

The primary object of the present invention is to provide a meanswhereby the cotton will be more effectually fed to the saws to insurethe operation of the saws at their full capacity when cotton is presentto be operated upon and, further, to improve the quality of the cottonby preventing breakage of the fibers and by removing the fiber from theseed more effectually.

A further object of the invention is to provide a means whereby thecotton may be more effectually and rapidly separated from the hulls,leaf-trash, dust, dirt, gravel, etc., and whereby the necessity forstopping the feeding of cotton to the gin in order to ef fect thedischarge of hulls, leaf-trash, etc., is avoided.

The invention is particularly applicable for use or embodiment in whatare known as huller gins, although it may be used to advantage in any ofthe ordinary types of gin now in common use, such as the usual plaingin, or in delinting machines, commonly known as linters, etc., etc.,and while l I do not wish to be restricted to any particular type ofgin, I have adopted a huller gin as the type best adapted forillustrating the application of the invention.

The invention consists primarily in a cotton handling device or meanslocated within the cotton chamber or breast of the gin but in front ofthe saws and ribs and adapted to impart to the cotton within the breasta movement transverse to the plane of the saws as well as a movementtoward the saws, the movement transverse of the plane in which the sawsrotate being such that the Specification of Letters Patent.

body of cotton presented to the saws is caused to sweep back and forthacross the face of a plurality of such saws and at the same time be fedin toward the saws or in a direction contrary to the direction in whichthe cotton not engaged by the saw teeth would be thrown by the action ofthe saws alone. WVhile the invention may take the form of any one of anumber of different de vices adapted to directly engage the cotton, itembodies in all instances a rotary carrier extending parallel with theaxis of the saw cylinder and having upon it a multiplicity of diagonallyarranged cotton engaging members which will force the cotton alternatelyback and forth in front of the ginning saws in a direction parallel withthe axis of the rotary carrier and saw cylinder. The necessary extent ofsuch movement is variable within wide limits, although practically itshould have a range equal to not less than the distance between severalof the saws and the cotton engaging members on the rotary carrier shouldbe so located or spaced with relation to each other that each and everyportion of the cotton being presented to the saws will partake of thisreciprocatory or back and forth movement in front of or across the edgesof the saws themselves, whereby the formation of channels or grooves inwhich the saws may run without engaging cotton in the breast iseffectually prevented.

Referring to the accompanying drawingsFigure l is a perspective view ofa gin of that type commonly known as a double rib huller gin, the outeror hulling breast having been removed and lowered to the floor in orderto disclose the saw cylinder and the outer portion of the casing of thebreast having been removed in order to disclose the spiked roller andthe means whereby the cotton is presented to the saws in accordance withthe present invention. Fig. 2 is a detail elevation of a shaft orcarrier having cotton engaging and handling devices thereon of thepreferred type. Fig. 3 is a sectional view through the gin breast andsaw cylinder of the type of gin illustrated in Fig. 1. Fig. 4 is asimilar view of a type of gin commonly known as a single rib huller ginto show the application of the invention to gins of this type. Figs. 5and 6 are detail front and end elevations of a modified form of cottonfeeding and han receives the cotton from any suitable the hulls,leaf-trash and other foreign matter is discharged. The cotton is carriedinto the inner chamber and thence through between the inner ribs to thebrush or other means whereby it is removed from the saws.

In the particular type of gin illustrated in Figs. 1 and 3 outer ginribs E separate the two chambers G and D while in the type of ginillustrated in Fig. 4 the gin ribs B are formed at B of such shape as toeffect the separation of the chambers and in both instances the spikedroller F is located at the lower end of the outer chamber in the usualposition.

All the parts so far described are of usual construction and form nopart of the present invention save in so far as they may enter into thenovel combination necessary in producing the advantageous results due tothe employment of the invention, as will be now pointed out.

In accordance with the present invention, a rotary carrier G which maybe in the form of a shaft or its equivalent is extended parallel withthe saw shaft but in front of the saw cylinder, being preferably mountedor supported in this position by bearings g in the end frames of the ginbreast. This rotary carrier or shaft G is provided with a multiplicityof diagonally arranged cotton engaging members which may be of variousforms. As shown in Figs. 1, 2, 3, and 4 they are in the form ofdiagonally arranged oval shape disks H which, when viewed in frontelevation, as in Fig. 2, are seen to occupy parallel planes diagonalwith relation to the axis of the carrier and when viewed in endelevation, as shown in Figs. 3 and 4, appear to be substantiallycircular. This circular appearance corresponds to their path of travelin rotating about the axis of the carrier. The peripheries of the cottonengaging members do not pass in between the saws but are adapted to passin proximity to the edges of the saws and intersect the planes of thesaws. If desired, they may be set at such an angle that theirperipheries will pass successively in proximity to a number of proximatesaws, the object being to force the cotton to travel back and forthlongitudinally of the saw cylinder and by the rotation of the cottonengaging members be also forced in against the edges of the saws inposition for the saw teeth to engage thercwith, whereby the fiber willbe carried away and the saws will operate at their full capacitywhenever any cotton is present.

In the type of gin illustrated, the cotton handling device is locatedimmediately above the spiked roller and operates to give a number ofadvantageous results in addition to its function of feeding the cottonto the saws, thus, it supports the weight of the mass of the cotton inthe gin breast, leaving the spiked roller free to perform its intendedfunctions of discharging the hulls, trash, and foreign matter. It alsoassists in shaking foreign matter out of the cotton and assists inpreventing the discharge of any of the lint which might tend to followthe spiked roller without being engaged by the saw and, finally, itforces any cotton thrown away from the saws by their action, to beimmediately returned to the saws where it is caught and carried off.

The device forms with the spiked roller a gradually contractingpassageway which forces all the cotton into engagement with the saws.

Various forms of cotton engaging and handling members will suggestthemselves and I have illustrated herein four of such forms, although Ido not wish to be restricted to the particular forms illustrated or toany particular form save where particularly specified in the claims.

In Figs. 5 and 6 the shaft which in this instance is shown as a solidshaft G is provided with a series of pins H arranged in diagonal planesand the distance between the succeeding series of pins is such thatcotton engaged and moved in one direction by one series will be engagedand moved in the opposite direction by the adjacent series being thusgiven a back and forth movement longitudinally of the axis of the shaft.In Figs. 7 and 8 the shaft or carrier G is shown in the form of a hollowshaft or pipe and provided with a series of diagonally arranged cutflights or disks H while in Figs. 9 and 10 a carrier G is shown providedwith a series of angular pins H set at such an inclination with relationto each other that the pins on one side of the shaft will tend to movethe cotton in one direction and the pins on the other side of the shaftwill tend to move the cotton in the opposite direction longitudinally ofthe shaft.

In all the arrangements it is preferred that the cotton engaging membersshould be so arranged that the cotton being presented to the sawsthroughout the whole length of the shaft or carrier and saw cylinderwill be moved simultaneously in one direction or the other and at thesame time rotary motion is imparted to the carrier and cotton engagingmembers as well as to the cotton senses which is engaged thereby, therotary movement of the carrier and cotton engaging members beingpreferably imparted through a pulley I (Fig. l) on the end of the shaftwhich may be driven by a belt K or other suit-able connections, wherebya sutficient speed of rotation may be imparted.

The direction of rotation should be in the opposite direction to thedirection of rotation of the saw cylinder whereby the proximate edges ofthe cotton feeding and handling device and saw cylinder move in the samedirection.

Having thus described my invent-ion, what I claim as new and desire tosecure by Letters Patent of the United States, is
